BACKGROUND

1. Field

The present invention relates to a novel compound and an organic electronic device using the same.

2. Description of Related Art

It is well known that organic light emitting device (OLED device) was initially invented and proposed by Eastman Kodak Company through a vacuum evaporation method. Tang and VanSlyke of Kodak Company deposited an electron transport material such as Alq₃ on a transparent indium tin oxide (abbreviated as ITO) glass formed with an organic layer of aromatic diamine thereon, and subsequently completed the fabrication of an organic electroluminescent (EL) device after a metal electrode is vapor-deposited onto the Alq₃ layer. The organic EL device currently becomes a new generation lighting device or display because of high brightness, fast response speed, light weight, compactness, true color, no difference in viewing angles, without using any LCD backlight plates, and low power consumption.

Recently, some interlayers such as electron transport layer and hole transport layer are added between the cathode and the anode for increasing the current efficiency and power efficiency of the OLEDs. For example, an organic light emitting diode (OLED) 1′ shown as FIG. 1 is designed to consist of: a cathode 11′, an electron injection layer 13′, a light emitting layer 14′, a hole transport layer 16′, and an anode 18′.

Recently, for effectively increasing the lighting performance of OLEDs, OLED manufactures and researchers have made great efforts to develop different compounds used as the materials for the OLEDs. However, in spite of various compounds have been developed, the current phosphorescence OLEDs still cannot perform outstanding luminous efficiency and device lifetime. Accordingly, in view of the conventional or commercial materials for OLEDs still including drawbacks, the inventor of the present application has made great efforts to make inventive research thereon and eventually provided novel compounds for OLED.

Step 1: Synthesis of Spiro Alcohol

To the intermediate C1 (1.0 eq) in anhydrous THF (0.4 M), n-BuLi (1 eq) was added dropwise and stirred at −78° C. After stirring for 20 min, intermediate B4 (0.7 eq) was added to the mixture and the reaction mixture was allowed to warm to room temperature. The reaction was monitored by HPLC. After completion of a reaction, the reaction solution was quenched with water, and a water layer was extracted with ethyl acetate. The extracted solution and an organic layer were combined and washed with saturated saline, and then dried with magnesium sulfate. After drying, this mixture was subjected to suction filtration, and then the filtrate was concentrated. 65 g of spiro alcohol was obtained as a light yellow, powdery solid and was directly used in step 2 without further purified.

To the obtained spiro alcohol (1 eq), acetic acid (w/v=1/3 to the reactant) and H₂SO₄ (5 drops) were added, and the mixture was stirred at 110° C. for 6 hr. The reaction was monitored by HPLC. After completion of a reaction, the precipitate was separated by filtration. The remaining substance was purified with column chromatography to obtain 58 g of intermediate D1 as white solid in a yield of 93.0%. FD-MS analysis C₃₁H₁₉Br: theoretical value 471.39, observed value 471.39.
